fix: use direct environment variables in CI instead of file mounting

- Revert to simpler approach of passing env vars directly to Docker with -e flags
- Change DATABASE_URL from PostgreSQL to SQLite for faster CI
- Remove file mounting complexity that was causing env var loading issues
- This matches the original working pattern but with SQLite instead of PostgreSQL
